RULESOrderNest guide

Order automation rules, and how to keep them safe.

An automation that edits orders can trigger itself on the edit it just made. Here is the shape of a rule, and the guard rails that stop that.

Updated 25 September 2026 · 3 min read · Verified against OrderNest's own code

A bulk edit is something you do. A rule is something you stop doing, you describe the decision once and it happens without you.

The catch is that a rule which edits orders can, in principle, trigger itself on the edit it just made. Tag an order, the order updates, the update fires the rule, which tags the order. Most of the design of a safe automation is about that one problem.

The three parts

A rule has three parts: a trigger: order created, updated, paid or fulfilled, a risk assessment, or a schedule over a segment; conditions combined with ALL or ANY across totals, statuses, risk, tags, SKU, vendor, geography and more; and actions: tag, note, archive, email on Starter and above, fulfil or cancel on Pro
When, if, then. The two guard rails at the bottom are what make the “then” safe to leave running.

The trigger is an order event, created, updated, paid, fulfilled, or a risk assessment arriving, or a schedule. A scheduled rule runs hourly, daily or weekly over a saved segment, and fires once per order, so a daily sweep does not re-process the same backlog every morning.

The conditions combine with ALL or ANY, and there are a lot of them: order total, item count, weight, payment and fulfillment status, risk level, order and customer and product tags, whether it is the customer's first order, discount code, SKU, vendor, product type, country, province, shipping method, gateway, currency, channel, and whether the order requires shipping.

The actions are the same vocabulary as a bulk edit: tag, note, archive, unarchive, and, on the right plans, email someone, fulfil, or cancel.

The two guard rails

Rules are loop-safe. A rule's own edit cannot re-trigger it. You do not have to build a "has not already been tagged" condition to protect against the obvious recursion; that is handled.

Fulfil and cancel require at least one condition. A rule carrying either of those actions cannot be saved matching every order. That is a deliberate refusal rather than a warning, and it exists because those two actions are the ones with no undo.

Start with Run now, even when auto-firing is available

Every rule has a Run now button, and it is on every plan including Free.

Use it as the rehearsal. Build the rule, run it by hand, read the per-order results, then turn on automatic firing once you have seen it hit the right orders. A rule you have watched run once is a different proposition from a rule you have only read.

Automatic firing is on Starter and above. On Free you get one rule and the button, which is honestly the right way round for learning the tool.

There are twelve templates to start from, and a visual builder. JSON stays available as the advanced path rather than the default, which is the right way round for a tool that edits live orders.

Running a rule from Shopify Flow

OrderNest ships a Flow action, "OrderNest: run rule", so any Flow workflow can fire a rule by name against an order. It needs no extra permissions, and the rule name is validated when you save the workflow rather than failing silently at 3am.

What matters is that it goes through the same path as a normal fire: dedupe per rule and order, counted against your quota, alerted on failure, and undoable. It is not a side door.

This is the answer when Flow can express the trigger you want but not the action, which is often.

Three rules worth stealing

  • Flag high-risk before you ship. Trigger on risk assessed, condition risk level is high, action add tag review. Then work that tag by hand.
  • Chase the stuck queue. A scheduled daily rule over an "unfulfilled more than 5 days" segment, action email someone. Nobody has to remember to look.
  • Mark first orders. Trigger on order paid, condition first order is true, action add tag first-order. Useful downstream for everything from packing notes to campaign segments.

What rules do not do

Worth stating plainly, because these are the adjacent things people assume: no order routing, no holds, no payment capture, no customer tagging, no packing slips. OrderNest edits orders: tags, notes, archive state, fulfilment and cancellation, and that is the whole surface.

FAQCommon questions

What can trigger an order rule?
An order being created, updated, paid or fulfilled, a risk assessment arriving, or a schedule: hourly, daily or weekly over a saved segment, firing once per order.
Can a rule fire itself in a loop?
No. Rules are loop-safe by design: a rule's own edit cannot re-trigger it. Fulfil and cancel additionally require at least one condition, so a rule with those actions cannot be saved matching everything.
Do rules run automatically on the free plan?
No. Automatic firing is on the Starter plan and above. Free gets one rule you can Run now by hand, which is enough to see exactly what it would do before you pay for it to happen on its own.
Can Shopify Flow run an OrderNest rule?
Yes. The app ships a Flow action, "OrderNest: run rule", so any Flow workflow can run a rule by name on an order. The name is validated when you save the workflow, and the run goes through the same path as a normal fire: deduplicated per rule and order, counted against your quota, and undoable. Starter and above; no extra permissions.
